7.11  Wiring of Units with Vspeed K Motor 

Vspeed variable speed fluid coolers use Nidec BPM motors which use KB VFD’s. The VFD’s come 
factory mounted in the control panel. Airflow is increased/decreased across the fluid cooler coil surface 
by modulating variable speed fans. 

The below figure shows wiring schematics for the drives and motors.
